refactor: replace Go binary with uv-run smartcommit.py launcher

The extension is now a bash launcher that runs smartcommit.py via
uv run --script (Crush backend, DuckDB scopes). Removes the Go
implementation and the gh-extension-precompile workflow; the bundled
gh-commit.tar.gz now packages the script instead of a compiled binary.

 # gh-commit
 
-AI-powered scoped git commits. Groups changes by project area, generates commit messages with `crush run`, and pushes — all in one command.
+AI-powered scoped git commits as a GitHub CLI extension, driven by the
+[Crush](https://github.com/charmbracelet/crush) CLI. Scopes map Conventional
+Commit scope names to path prefixes. They are generated from the repository
+file tree, stored in a local DuckDB database, and auto-regenerate whenever
+`.gitignore` changes. Changed files are grouped by scope and committed one
+scope at a time with generated `type(scope): message` subjects.
 
 ## Install

 ### Requirements
 
 - [uv](https://docs.astral.sh/uv) — Python package runner (handles dependencies automatically)
-- [Crush](https://github.com/charmbracelet/crush) — non-interactive AI runner
-- `GROQ_API_KEY` — authenticates the default Groq model
+- [Crush](https://github.com/charmbracelet/crush) — configured with an authenticated model provider
 
-By default, gh-commit uses Groq's `openai/gpt-oss-120b`. Override the model with `GH_COMMIT_CRUSH_MODEL`.
+By default, gh-commit uses `openrouter/qwen/qwen3.6-27b`. Configure OpenRouter in Crush or override the model with `GH_COMMIT_CRUSH_MODEL`.
 
 ## Usage
 
 ```sh
-# Initialize scopes for your repo (uses Crush to analyze structure)
-gh commit init
-
-# Commit changes grouped by scope
-gh commit
-
-# Auto-confirm + auto-push
-gh commit --auto --push
-
-# Manually refresh scopes after structural changes
-gh commit refresh
-
-# Sync scopes as GitHub labels
-gh commit sync
+cd your-repo
+gh commit init   # generate scopes for this repo
+gh commit        # commit changes grouped by scope
 ```
 
-## How it works
-
-1. **`gh commit init`** — `crush run` analyzes your repo structure and generates scope definitions (e.g., `core → src/`, `docs → docs/, README.md`, `ci → .github/workflows/`)
-2. **`gh commit`** — Groups dirty files by scope, sends each staged diff to `crush run`, and commits each group separately
-3. **Auto-refresh** — Whenever your `.gitignore` changes, scopes are automatically regenerated before committing (a content hash of `.gitignore` is tracked per repo)
-4. Remaining unscoped files are handled in a final pass
-5. Unpushed commits are offered for push
-
-Scopes are stored in a local DuckDB database (`~/.local/share/gh-commit/gh-commit.db`) — no config files in your repo.
-
-### Why Crush?
-
-The former Mods roles now live directly in `smartcommit.py`, so gh-commit no longer depends on Mods configuration. Each generation invokes Crush's supported non-interactive mode with a self-contained prompt.

 ## Commands
 
-| Command | Description |
-|---------|-------------|
-| `gh commit` | Commit changes grouped by scope |
-| `gh commit init` | Generate scopes for current repo |
-| `gh commit refresh` | Update scopes from current structure |
-| `gh commit sync` | Sync scopes → GitHub labels |
-| `gh commit list` | List all configured repositories |
-| `gh commit remove` | Remove current repo from database |
-| `gh commit db-path` | Print database file path |
-| `gh commit version` | Print version |
-| `gh commit help` | Show help |
+| Command | Behavior |
+|---|---|
+| `gh commit` | Full scoped-commit flow: group changed files by scope, generate a message per group, confirm, commit, offer to push |
+| `gh commit init` | Generate scopes from the file tree via Crush; migrates legacy configs; confirms overwrite |
+| `gh commit refresh` | Show current scopes, regenerate with existing scopes as context, confirm apply |
+| `gh commit sync` | Create/update GitHub labels from scopes (color = first 6 hex chars of MD5 of the scope name) |
+| `gh commit list` | Table of configured repositories: name, path, scope count |
+| `gh commit remove` | Delete the current repo from the database after confirmation |
+| `gh commit db-path` | Print the database file path |
+| `gh commit version` | Print `gh-commit <version>` |
+| `gh commit help` | Help, including the DB path and environment variable docs |

+## Storage
 
-Existing `.github/Repo.toml` or `.github/scopes.json` files are automatically detected and migrated to DuckDB on first run.

+(DuckDB). Legacy `.github/Repo.toml` and `.github/scopes.json` files are

+```sh
+mkdir /tmp/accept && cd /tmp/accept && git init
+mkdir -p src docs
+echo 'package app' > src/app.go
+echo '# Docs' > docs/README.md
+gh commit init          # scopes generated and saved

+```
+
+## Development
+
+The extension is a bash launcher (`gh-commit`) that runs `smartcommit.py`
+with `uv run --script`; uv resolves the inline dependencies (duckdb, rich,
+questionary) automatically.
+
+```sh
+python -m py_compile smartcommit.py   # syntax check
+bash -n gh-commit                     # launcher check
+./gh-commit version                   # smoke test
+```
